We introduce, for the first time, optical flow tracking on 360 footage taking into account the connectedness of the left and right sides of the 360 video, as well as taking into account the geometry of the top and bottom edge pixels.This means that when blurring 360 video that you don't see artifacts along the edges of the video that you might see with previous versions of our products, and with other optical flow-based techniques.
In this example RSMB is used to blur the automatically tracked 360 source video. Then a rectilinear projection is used that centers the left/right edges of the blurred 360 video.
